ASH SIFTEBJ.

Application filed June 3,

The present invention relates to ash sifters for fitting over andclosing the end of an ash receptacle and for inclosing a movable sieve for the purpose of confining dust which arises during sifting.

An obj cct of the inventionis to provide an inclosed ash sifter which will lit and close ash the invention is to provide a siftcr having a sieve which is easily and quickly removed or inserted. tagcs of the invention will appear from the following particular description of a form of siftcr embodying the invention and from an inspection of the accompanying drawings; and the invention also consists in certain new and useful features of construction and combinations of parts herein set forth and claimed.

In the accompanying drawing, in which like reference characters refer to the same parts throughout, there is shown for purposes of illustration a form of apparatus embodying the invention, in which: Figure 1 is a disassembled view in elevation of a sifter of the invention and a cover therefor, Figure 2 is a plan view of a casing member of the apparatus of Figure 1, Figure 3 is an elevation view in section and in part cut away showing the sifter casing and a sieve therein, Figure 4 is a vertical sectional view of the sifter mounted on a barrel, Figure 5 is a horizontal sectional view taken along the line 55 of Figure 41 of the sifter without the cover and with a sieve therein and Figure 6 is a front elevation view of the sieve.

In the drawings the cylinder 1 of sheet metal is rolled outwardly along its upper edge and headed over a ring 2 and at its lower edge it is turned and crimped inwardly upon itself. Intermediate its ends said cylinder 1 has an annular head 3 which carries an outwardly extending and downwardly slanting annular flange 4 from which depends an annular skirt 5, said skirt 5 being spaced apart from the wall of cylinder 1 to provide an annular channel 6 which will fit over the edge of an ash barrel 7 The said channel 6 is provided of sullicient width to fit several sizes of barrels or cans. Said flange 4 serves as a cover part as well'as a support, and a top cover 8 covers the top of cylinder 1. Above said flange l said cylinder 1 defines the horizontal slot 9 and also diametrically opposite thereto the horizontal slot 10. Slot 9 con Another object of Various other objects and advan-.

nects with the upwardly extending slot 11 which reaches through the upper edge of the cylinder 1 and cuts through said ring 2, and said slot 10 connects with a slot 12 whichis diametrically oppositeslot 11 and extends upwardly for a distance from slot 10. A red 13 supports a cylindrical sieve 14 and extends therefrom at diametrically opposite sides, with a handle 15 on one end, and the sieve 15 is positioned in cylinder by inserting the outer endof rod 13 through slot 12 and the handle end intoslot 1.1 and dropping the rod 13 onto the le ver edges of said slots 9 and 10. An annular flange 16 carried by sieve 1 1 errtends to within a short distance of the inner wall of cylinder 1 and serves a closure against dust which might tend to pass upwardly from below the sieve during the sifting or afterward. An arcuate flange 17 carried on the inner wall of cylinder 1 serves with said flange 16 as a guide to hold the sieve 1 1 in a horizontal position on its suporting rod and particularly during the movement of the sieve in sifting. The strips 18, 18 fixed to the wall of cylinder 1 serve as bracing and strengthening members for the portions adjacent to slots 9 and 11. An annular band 19 fixed to the inner surface of the cylinder of sieve 14 secures a sifting screen 20 in place therein. A hook shaped handle member 21 mounted on sieve 1 1 opposite handle 15 serves as additional means for handling the sieve to put it, in place in and to remove it from the cylinder 1.

In the use and operation of the sifter of the invention the member 1 is placed over the end of an ash receiving barrel with channel 6 over and about the edge thereof in which position the flange 4 will partly close the barrel. The sieve 14; is then mounted in the cylinder 1 by inserting the outer end of rod 13 through slot 12 into slot 10 and dropping the handle end of said rod 13 through slot 11 onto the bottom edge of slot 9. The sieve 14 I is then supplied with a charge of ashes to be sifted and the closure of the barrel 7 completed by placing cover 8 on cylinder 1. The ashes are sifted by moving the sieve by means of handle 15 and in an oscillatory movement as permitted by said slots 9 and 10. The members defining channel 6 together with flange 16 and screen 20 and the cinders and clinker-s thereon serve to prevent the passage of any substantial amount of dust from the barrel 7 and the upper part of cylinder 1 and its cover 8 will bar the escape of dust from the top of the sieve l4.

lVhile there is shown and described, and pointed out in the annexed claims certain novelfeatures of the invention, it will beunderstood that various omissions, substitutions and changes in the forms and details of the devices illustrated may be made with:

out departing tion.

I claim: V 1. in an ash sitter, in combination, an infrom the spirit of the invenverted annular channel member of sheet metal adapted to fit over the edge of ash barrels of various sizes, a cylinder registeringwith and extending upwardly from said channel member, said cylinder having formed therein dias metrically opposed horizontal slots and a slot extending upwardly from one of said horizontal slots through the edge of the cylinder, a cylindrical sieve fitting in said cylinder and rotatable therein, an annular dust baflie flange extending from said sieve with its margin fitting closely to the wall of said cylinder and acting to close off the upward I assa e of dust from below said sieve a su b 7 port rod extending from said sieve through each of said horizontal slots, and a handle o 1st day of June 1927.

for the rod at the side having the upwardly extending open ended slot.

2. In an ash sitter adapted'to fit over ash barrels of various sizes, a member of sheet metal'having an upwardly extending annular wall and. downwardly extending double walls defining an annular channel, said upwardly extending wall having diametrically opposed horizontal slots and a slot extending upwardly from one of the horizontal slots through the'upper edge'thereof, an annular sieve fitting in said annular wall and having a diametrically extending support rod slidable in said horizontal slots, one end portion of said sieve during actuation thereof, and a top cover for said annular wall.

In testimony, that I claim the invention set forth above I have hereunto set my hand this ISAAC LEIBOWITZ.
